Montreal, Canada – November 7, 2019 – Theratechnologies Inc. (Theratechnologies) (TSX: TH) (NASDAQ: THTX), a commercial-stage biopharmaceutical company, is pleased to announce that data presented at the 17^th European AIDS Conference, currently being held in Basel, Switzerland, demonstrate that Trogarzo^® (ibalizumab-uiyk) remains safe and effective in patients having been on treatment for almost a decade.

Results come from a sub-analysis of patients enrolled in study TMB-311.  Patients in TMB-311 were enrolled in one of two cohorts. Cohort 1 included 12 patients rolled over from an Investigator-sponsored Investigational New Drug (PI-IND) protocol upon completion of TMB-202, a Phase 2 clinical trial of Trogarzo^®. Cohort 1 also included 27 patients who had participated in the Phase 3 clinical trial TMB-301.

At time of last TMB-311 visit, all 12 patients rolled over from the Phase 2 clinical trial had an undetectable viral load. Those patients had been treated with Trogarzo^® and an optimized background regimen for 7.8 years to 9.5 years (average 8.8 years).

Viral load suppression in patients rolled over from TMB-301 was achieved in close to 60 percent of participants (16/27).

TMB-311 also included 38 patients who had no prior history of treatment with Trogarzo^®. Those patients were part of Cohort 2. After 48 weeks of treatment, 46% of Cohort 2 patients still on treatment achieved a viral load below 50 copies/mL (8/17).

In all cohorts, Trogarzo^® was well tolerated and no ibalizumab antibodies were observed in any patient.
